Abstract
An energy-absorbing support structure has an absorbing body including a fiber-reinforced plastics material. The latter is arranged between a support structure abutment component and a support structure impact-absorbing component. The absorbing body absorbs energy by deforming from a starting state into a deformed deformation state based on an impact-induced relative displacement of the support structure components, the energy being introduced into the support structure by an impact. The absorbing body is configured as a body which has already been predeformed in the starting state by energy absorption compared to an original state. During production of the support structure, the absorbing body is firstly produced in the original state, the latter is then predeformed into the starting state and finally the absorbing body is connected to the support structure components. The result is a support structure which absorbs energy in a predictable and defined manner upon an impact-induced introduction of energy.
